STEGOMYIA 



797 



Unfortunately its name is about to be changed either to S. calopus Meigen 

 or S. frater Desvoidy. Theobald at present is not certain which will prove 

 to be the correct term. The name as it stands at present is 5. fasciata

Fabricius, 1805 {non O. F. Miiller, 1764) (synonyms: Culex calopus Meigen, 

 1818 (?), C. frater Desvoidy, 1827). O. F. Miiller, it appears, used the term 

 ' fasciata ' for a Culex in 1764.
